llVlPROVED EVAPORATO R.

To all whom it may concern:

Be itknown that I, L. R. GLEASON, of Dundee, in the county of Yates andState of New York, have invented a new and useful Improvement inAtmospheric Evaporators for the Manufacture of Salt from Natural Brine;and I do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,in which- Figure l is a perspective view, and Fig. 2 a section, of theframe-work of the same, and in which like letters refer to like parts.

I generally construct my evaporators of wood.

A A are posts; B B, girders. O O are also girders. D D are removablepinsf E E are tables. F F are notches, and G G are points at the lowestend of the tables. H is a trough. 1 2 3 4 are taps'and faucets. I is avat.

The posts and girders are the frame-work or scaffolding.

The girders G G are supports to tables. The removable pins are alsosupports of some of the lower tables at one end. These pins may be takenout to let one end otla table down upon the one below it to facilitatethe removal of the salt that crystallizes on the table.

The upper surface of the tables is formed into shallow channels andridges running from one end to the other. One end of each table is lowerthan the other. The first has an inclination downward in one direction.The second has an inclination downward in the direction opposite to thatof the first. The inclination of the third is like that of the first;the fourth like the second. The tables sustained between one set ofposts are called a stand? Several stands united together are called aran ge. Any desired number of tables may be used in a stand, eachinclining downward in the direction opposite to the one above it. Thehighest end of each table projects farther than the lowest end of thetable next above it. The lowest end of each table is notched in itslowest edge to form points under the channels of the same table and overthe channels in the table below it.

Brine is supplied to the trough and fed through the faucets into thechannels of the first table. It flows to the lowest end of the table andfalls from the points into the channels of the second table at thehighest end. It passes from the second table to the third, and so onfrom one table to another to the last. The brine is conveyed all overthe tables in channels at small distances apart, and its attraction tothe wood causes it to spread toward the ridges. When the brine isproperly fed through the faucets all or nearly all of the upper surfaceof the tables is kept wet. If the water of the brine is not allevaporated before itleaves the last table, the vat receives it.

The more brisk the wind, and at the same time the more dry and warm theatmosphere. the faster the flow of brine is required from the trough.While there is little or no wind and the air contains much vapor and isless warm, evaporation being slower, feed from the trough should beproportionately slower.

The object in using tables of such form in such a manner is to furnishthe largest amount of evaporating-surface possible with the leastproportionate expense of building and tending, and thereby producing aquick and cheap method of making salt from brine by atmosphericevaporation.

I do not claim the use of posts and girders, or ofa trough or vat, ortables placed one above another in evaporators as my invention, as suchthings, including tables with raised edges and holes at their lowestends, are described in Barruels Practical Chemistry.

l/Vhat I do claim as my invention, and desire to secure by LettersPatent, is-

1. The channeling of tables, which allows of using broad tables.

2. The use of faucets to feed the brine upon the first table and toregulate the feeding according to the condition of the atmosphere.

3. The depending points, in combination with projecting ends of tablesfor directing the drip from one table to another correctly.

4. The removable pins, or their equivalent, for the purpose specified.
